I want to make a user login page inside my app and when user will login through facebook or google then i will get the email id database of those users

actually i figure out a plugin on clickstore but i don't know that it will allow me store the emails of my users?
as there is no contact details of seller on the clickstore - https://clickstore.clickteam.com/plugins/tools/login_system_online_starter_kit


but if anyone can help me then please reply i can pay for that .
